Title: Manufacture of magnetic recording medium
Inventor: OOIWA TSUNEMI
IPC: G11B5/84
Filed: 1983-09-16
Abstract: PURPOSE:To improve the durability of a magnetic recording medium, by forming a compact and hard plasma polymerized protective film layer of an organic compound by moving a base body on which a ferromagnetic metallic thin layer is formed along the peripheral side face of a cylindrical can and, at the same time, performing plasma processing by introducing a monomer gas of the organic compound to a space between a trough-like shielding frame and the cylindrical can from a side from which the base body is introduced. CONSTITUTION:Since plasma processing is performed by introducing a monomer gas of an organic compound to a space 10 formed between a trough-like shielding frame 11 and cylindrical can 4 from a side from which a base body 1 is introduced, plasma polymerization successively proceeds as the base body 1 moves and, because of the gas pressure being high at first, a plasma polymerized material of the organic compound having a relatively low molecular weight and a good adhesion is adhered to the surface of the ferromagnetic metallic thin layer on the base body 1 with a good adhesiveness. Then, as the gas pressure becomes lower, a hard and compact plasma polymerized material having a relatively high molecular weight is adhered and as approaching to the surface a more compact and harder plasma polymerized protective layer is formed.

IPC: G03G15/20
Filed: 1982-09-30
Abstract: PURPOSE:To improve the heat absorption efficiency in heat fixation and to improve the reliability and the durability of a device by making the roughness of the internal surface of a rotating body higher in the internal-surface end area than in the center area so that the end area has higher heat absorptivity than the center area. CONSTITUTION:The internal surface roughness of a cylinder with a uniform diameter which is manufactured by a drawing method is <=1mum, the heat reflectivity is large, and the heat absorptivity is small. Then, the entire internal surface is roughened into an about 3mum nearly-uniform rough surface and then the end part is roughened as shown by R to about 8mum. The external surface temperature distribution of the fixation roll which is roughened to 3mum roughness both in the center area S1 and end area S2 shows a greater temperature drop in the end part area, but the fixation roll R has nearly uniform temperature distribution. Consequently, the heat of the end area is absorbed by the fixation roll efficiently, the temperature rise of air outside of the roll of a member is suuppressed extremely, and the heat absorptivity is increased to improve the reliability and durability.

Title: Check valve
Inventor: MORI KOUHEI
IPC: F16K15/03
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To hold a sufficient opening even in a low flow rate without lowering the strength of a check valve by providing the check valve with a valve element with a floating body attached thereto suspended over a flow passage by a dead weight and opening only by a forward-directional fluid pressure. SOLUTION: A floating body 10 using a material having a large buoyancy such as a metal plate or a synthetic resin plate hollow box and an independent synthetic resin foam block body is provided in a rear side of a valve 4 in a position without any contact with a stopper. The valve is suspended over a flow passage by the dead weight and opened only by a forward-directional fluid pressure. That is to say, the rotation moment about a fulcrum 5 in a pipe filled state offsets a right-handed rotation moment Mw by the dead weight of the valve element 4 and the left-handed rotation moment Mb by the buoyancy of the floating body 10 so that the valve is rotated in its closing direction by a slight right-handed rotation moment Mbw. This constitution can hold the sufficient opening even for a small flow rate.
